Which type of antenna is typically used for mobile operations due to its compromised size and efficiency?

• A. Yagi antenna
• B. Dipole antenna
• C. Whip antenna
• D. Loop antenna

Answer: (C)

The whip antenna is commonly used for mobile operations because of its compact size and reasonable efficiency. This type of antenna is typically flexible, making it practical for installations on vehicles where space is constricted and where durability is important. The whip antenna can be easily adjusted and extended, which helps optimize performance across various frequencies while remaining portable and easy to handle.

In contrast to the whip, other antennas like the Yagi and dipole are generally larger and less suited for mobile applications. A Yagi antenna, for instance, is designed for high gain and directivity, which means it tends to be longer and is better suited for fixed installations. The dipole antenna, while versatile and effective, also requires more space for proper operation and is often used in stationary setups. A loop antenna can be compact but typically does not perform as well in mobile applications as a whip antenna, especially in terms of efficiency and ease of use in varying environments.

Overall, the whip antenna's design and characteristics make it the ideal choice for mobile operators who need an efficient yet compact antenna solution.
